I would like to see the drawing, but didn't find an attachment

Chuy:
I have attached a crude drawing of a cross-sectional view of the hull and
deck joint. As you will see, the sealant goes in the space between where the
hull and deck overlap. Ideally it would be best to remove the rivets in
order to open the gap in order to remove the sealant. That requires the
removal of the rub rail and chances are that the rail will be destroyed in
the process. Once the sealant is forced into the gap the gap is closed with
new rivets or bolts. You would do this in sections rather than all at once.
The easier alternative is to just remove whatever sealant you can from the
join and add sealant at the bottom of the gap but that will be a temporary
fix based on my experience. 

I can't see where putting sealant on either side of the rub rail would
accomplish much of anything other than make a mess. It is the gap that needs
to be sealed, not the rub rail.

The rivets on my deck hull join held firmly for 35 years but if I were to
replace them I would probably use bolts and at closer intervals to give less
movement to the join area. But I have already glassed the join on the inside
so any hardware is probably redundant anyway.

I will be interested to see what Rummy's strategy is.

  Yes, the aluminum track with the black plastic.  When Stan riveted the rub
rail, he joined the top half to the bottom half of the boat.  So ,there is a
seam where the top part meets the bottom part. My question refers to how
these two parts meet.  Does the top half overlap the bottom, there they are
riveted?  On my Rhodes the top half appears to slide down and to the outside
of the hull half.  The rivets are then inserted into the two halves. The
rivets after a time will make the hole larger allowing water to enter the
boat in some cases to enter the cabin or the cockpit.

Does this sound right to you.  I had wanted to redo the aluminum track but I
do not want to use rivets.  Would rather use bolts but there are some areas
where I can not get to the inside to place the nut.  I I think screws would
be worst than rivets.  A few people replied that they had silicone the top
and bottom of the rail and it seemed to be working.  So, I will try it.  It
seems to me, that unless the holes get very large the leaks can be contained
with a seal on the rail.

I do have another question for you.  The doors inside the galley use a
track.  You had mentioned that you are using or will be using some track
from Lowe's, can you give me more details on the track you plan on using and
also the type and thickness of material you plan on using on the top and
bottom galley doors.

Thank for taking the time to answer all my questions and concerns.

Happy Holidays,
